Description

Technical Field:

[0001] The present invention belongs to the technical field of agricultural machinery and equipment, and particularly relates to a garlic planter for realizing large-scale and mechanized sowing of garlic. Background Art:

[0002] A garlic planter is a kind of agricultural planter urgently needed in current agricultural production. When sowing garlic, it is first necessary to ensure that the garlic seed scales face upwards. If the scales face downwards, germination may not be possible. If they lie flat, it will lead to uneven growth, thus affecting the yield. It is necessary to ensure that the spacing between garlic seeds is consistent. Taking the garlic base in Pingdu, Qingdao as an example, the spacing between garlic seeds is 8 cm. Less than 8 cm will affect the yield of garlic scapes, and more than 8 cm will waste land. It is not possible to have multiple garlic seeds in one hole or miss sowing. It is necessary to ensure that the garlic seeds are in a straight line during sowing. A curved sowing line will affect operations such as laying drip irrigation, ridging, and film covering. It is necessary to ensure that the depth of the garlic seeds is the same. Sowing the garlic seeds too shallow will cause them to lie flat and unable to stand upright, and sowing them too deep will make it impossible to directly observe whether there is a shortage of seeds and will also affect the emergence rate. Finally, it is necessary to ensure the reliability and cost-effectiveness of the machine.

[0003] The existing garlic planters in the prior art are either too low-end to meet the requirements of farmers or too complex and expensive, especially those using a heavy crawler chassis and electrification control. The sowing action is achieved through actuators such as cylinders and oil cylinders, and it is difficult to guarantee their service life under the production conditions of the farmland field environment.

[0004] As Figure 1 shown, in order to ensure accurate sowing and the uprightness of garlic, a duckbill planter is selected for the garlic planter. In order to ensure production efficiency, the garlic planter needs to complete the sowing action while moving forward. The running track of the duckbill planter is similar to an ellipse to ensure that the duckbill is basically stationary relative to the ground when it enters the soil. Based on this, a general technical solution selects a crank and connecting rod mechanism. However, this cannot solve the power source problem of the duckbill action because it is difficult to use a mechanical transmission method to open and close the duckbill due to the elliptical movement track of the duckbill planter. Therefore, there appears as Figure 2The technical solution shown uses various actuators such as oil cylinders, air cylinders, electric cylinders, etc. For example, Chinese Patent No. 201721316638.1 discloses a garlic seeder, comprising a frame, a driving mechanism, a sowing mechanism and a lifting and steering mechanism; a driving mechanism is arranged on one side of the frame, and the driving mechanism comprises an engine unit, a hydraulic drive unit and a gearbox arranged at the upper part of one side of the frame, and a grooved parallel drive roller is arranged at the bottom of the frame, one side of the grooved parallel drive roller is drivingly connected to the hydraulic drive unit, and the other side is drivingly connected to the gearbox, and the engine unit is drivingly connected to the hydraulic drive unit; the sowing mechanism comprises a seed box, a seed taker unit and a plurality of seed outlet channels, the seed box is arranged at the upper part of the other side of the frame, the seed taker unit is longitudinally arranged and at least partially extends into the seed box, the seed outlet channels are longitudinally arranged in parallel at intervals, and the top of the seed taker unit is connected to the top of the seed taker unit, and the seed taker unit is drivingly connected to the gearbox; the lifting and steering mechanism comprises a hydraulic cylinder arranged vertically at the bottom of the frame, the hydraulic cylinder is fluidly connected to the hydraulic drive unit, and a rotatable base is provided at the bottom of the hydraulic cylinder. However, its service life under arable land production conditions is difficult to guarantee.

[0007] The rear end of the machine frame involved in the present invention is also provided with mutually connected drip irrigation and drip irrigation laying components; the jack is connected to the machine frame through a connecting rod; the lower shaft is connected to the front shaft through a No. 1 transmission component, the front shaft is connected to the rear shaft through a No. 2 transmission component, the rear shaft is connected to the rear wheel and the power mechanism through a No. 3 transmission component, and the lower shaft, the front shaft and the rear shaft rotate at the same speed; a plurality of garlic seed spoons are evenly spaced on the conveyor.

[0008] When the garlic seeder disclosed by the present invention is used, the ground height of the garlic seeder is raised by a jack, and after being towed and transported to a farmland, garlic seeds are poured into a garlic seed bin, the clutch is closed, the ground height of the garlic seeder is lowered by a jack, the depth of a duckbill seeder is adjusted, a drip irrigation laying component is buried in the soil, the engine is started, the clutch on the transmission is closed, and forward sowing begins.

A number of power shafts 361 of the duckbill seeders 36 can be connected in series through the first-shaped connecting rod 337. When the cam 335 rotates, it drives the driven roller 333 to perform a reciprocating lifting-lowering action, drives the I-shaped connecting rod 334 to move up and down through the lever 331, drives the L-shaped connecting rod 336 to swing left and right through the I-shaped connecting rod 334, makes the action shaft 361 rotate forward and backward, and further drives the duckbill seeder 36 to complete the opening and closing actions; the aligner 35 is connected to the seed guide tube 44, which is a garlic bud aligning device disclosed in Chinese Patent No. 20182214191.7, and the upward rate of the garlic bud of the garlic seeds is close to 100%; the driving shaft 42 is connected to the transmission 52 through a sixth transmission assembly 45; the garlic seed spoon 47 is of a cantilever structure, which can make the redundant garlic seeds fall off to ensure one garlic seed per spoon; the rear wheels 55 are driving wheels, and the number is an even number greater than or equal to 2; the rear axle 203 is connected to the transmission 52 through a third transmission assembly 206; the first transmission assembly 204, the second transmission assembly 205, the third transmission assembly 206, the fourth transmission assembly 211, the fifth transmission assembly 214, the sixth transmission assembly 45, and the seventh transmission assembly 53 adopt synchronous pulley transmission or sprocket transmission. Taking the fourth transmission assembly 211 and the fifth transmission assembly 214 as examples, their main structures both include a transmission wheel 200 and a transmission belt 300; the front crank short shaft 210 is connected to the front camshaft 31, and the rear crank short shaft 213 is connected to the rear camshaft 32. Their connection methods are the same. First, a connecting rod 100 is used to connect the short shaft and the camshaft. Then, transmission wheels 200 are respectively sleeved on the short shaft and the camshaft. Finally, the two transmission wheels 200 are connected through a transmission belt 300 to make the short shaft and the camshaft rotate at the same speed. Among them, the transmission wheel 200 on the short shaft is the driving wheel, and the transmission wheel 200 on the camshaft is the driven wheel.

[0023] The weight of the garlic planter involved in this embodiment is less than or equal to 200 KG. It is light in weight, with a seeding efficiency of 1 mu per hour and high reliability. When in use, the power of the engine 51 is transmitted through the transmission 52 and then outputs power at different speeds through 3 output ends, respectively driving the seeding mechanism 3, the garlic seed taking mechanism 4, and the rear wheels 55 to act. Different transmission ratios enable the 3 actions to cooperate with each other to achieve the purpose of seeding while advancing. The specific process is as follows:

[0024] Driven by the third transmission assembly 206, the lower shaft 201, the front shaft 202 and the rear shaft 203 rotate synchronously. Driven by the lower crank 207, the sowing mechanism 3 moves forward and backward. Driven by the front crank 209 and the rear crank 212, the sowing mechanism 3 moves up and down. The three groups of cranks are parallel to each other and rotate at the same speed. Regarding the sowing mechanism 3 as a point, its running track is an ellipse. When the duckbill seeder 36 inserts into the soil hole during the forward process, it remains relatively stationary with respect to the ground. When the front crank 209 and the rear crank 212 rotate, the driving wheels on the short axis 210 of the front crank and the short axis 213 of the rear crank transmit power to the front camshaft 31 and the rear camshaft 32 respectively through the fourth transmission assembly 211 and the fifth transmission assembly 214, so that the front camshaft 31 and the rear camshaft 32 rotate synchronously with the front shaft 202 and the rear shaft 203. During the operation of the sowing mechanism 3 along the elliptical track, the camshaft 31 and the rear camshaft 32 rotate at the same speed. The cam assembly 33 drives the duckbill seeder 36 to act through the rocker arm 34. When the sowing mechanism 3 runs near the lowest point of the elliptical track, the cam assembly 33 pulls the duckbill seeder 36 to start opening. After a set time when the sowing mechanism 3 passes through the lowest point of the elliptical track, the duckbill seeder 36 starts to close. In this way, the duckbill seeder 36 completes the reciprocating actions of entering the soil, opening, lifting and closing along the elliptical track.

[0025] Driven by the sixth transmission assembly 45, the driving shaft 42 rotates. Through the driven shaft 43 and the conveyor 46, the garlic seed spoon 47 is further driven to take out the garlic seeds from the garlic seed bin 41. The garlic seeds enter the aligner 35 through the seed guide pipe 44. When the first wave of garlic seeds enters the seed guide pipe 44, the duckbill seeder 36 is in the closed state. After the duckbill seeder 36 enters the soil and completes the sowing of the first wave of garlic seeds and lifts up, the second wave of garlic seeds just falls into the seed guide pipe 44. In this way, the actions of taking and putting in the garlic seeds are completed reciprocally.

[0026] Driven by the seventh transmission assembly 53, the drive shaft 54 rotates. The clutch 56 is closed, and the rear wheels 55 rotate synchronously with the drive shaft 54 to drive the garlic seeding machine forward. The forward direction of the garlic seeding machine is controlled by the handle 13. For every set length that the garlic seeding machine advances at a constant speed, the sowing mechanism 3 completes one sowing, and the duckbill seeder 36 remains relatively stationary with respect to the ground when it enters the soil. In this way, the sowing plant spacing is controlled reciprocally.
